Kell Brook has vowed to guard against complacency as he looks to move closer to a world welterweight title fight in Liverpool on Saturday night. The Sheffield fighter has been guaranteed a summer shot at the IBF belt currently held by American Shawn Porter - provided he dispatches Mexican Alvaro Robles at the Echo Arena.

Robles is no slouch having stopped all but two of his 17 victims inside the distance - but has also been frequently floored himself.

Brook said: "This is a very important fight and it is a banana-skin fight. It is important because if I don't win this there is no big one to follow. Robles is going to be game and he will want to take my head off. I am looking forward to the opportunity to get in there and show people what I can do."

Also on the card, Liverpool's Tony Bellew makes his cruiserweight debut against Russia's Valery Brudov in his first fight since losing his WBC light-heavyweight title challenge to Adonis Stevenson in Quebec in November.
